What connects multiple drainage fixtures to a common waste and vent pipe?

• A. A vertical stack
• B. A combination waste and vent system
• C. A main drain line
• D. A trap

Answer: (B)

The choice of a combination waste and vent system is correct because it serves a dual purpose of both waste removal and venting for multiple drainage fixtures. In plumbing systems, particularly in residential applications, this configuration allows for an integrated system where the waste from different fixtures, such as sinks, showers, and toilets, can flow through a single pipe structure while also providing necessary ventilation to prevent vacuum and allow for proper drainage. This system is designed to efficiently handle wastewater and air pressure balance, thus enhancing the overall performance of the plumbing system. Without a combination waste and vent system, each fixture would require separate venting, leading to increased material costs and more complex installations. Understanding the role of this system is crucial for ensuring that plumbing installations adhere to the International Plumbing Code, which emphasizes the importance of efficient waste removal and effective venting to maintain system health and functionality.
